The present invention claims priority to, and the benefit of U.S.Provisional Patent Application No. 61/934,944, filed on Feb. 3, 2014,which is herein incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to three new and distinctive garden beancultivars (Phaseolus vulgaris) designated H33121, H33122 and/or H33124.

BACKGROUND OF THE INVENTION

The disclosures, including the claims, figures and/or drawings, of eachand every patent, patent application, and publication cited herein arehereby incorporated herein by reference in their entireties.

The following description includes information that may be useful inunderstanding the present invention. It is not an admission that any ofthe information provided herein is prior art or relevant to thepresently claimed inventions, or that any publication specifically orimplicitly referenced is prior art.

There are numerous steps in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possesses the traits tomeet the program goals. The goal is to combine in a single variety animproved combination of desirable traits from the parental germplasm.

In beans, these important traits may include fresh pod yield, higherseed yield, resistance to diseases and insects, better stems and roots,tolerance to drought and heat, and better agronomic quality. Withmechanical harvesting of many crops, uniformity of plant characteristicssuch as germination and stand establishment, growth rate, maturity andplant height is important.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F₁ hybrid cultivar, purelinecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location may be effective,whereas for traits with low heritability, selection should be based onmean values obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, recurrent selection andbackcross breeding.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars.Nevertheless, it is also suitable for the adjustment and selection ofmorphological character, color characteristics and simply inheritedquantitative characters. Various recurrent selection techniques are usedto improve quantitatively inherited traits controlled by numerous genes.The use of recurrent selection in self-pollinating crops depends on theease of pollination, the frequency of successful hybrids from eachpollination and the number of hybrid offspring from each successfulcross.

Each breeding program should include a periodic, objective evaluation ofthe efficiency of the breeding procedure. Evaluation criteria varydepending on the goal and objectives, but should include gain fromselection per year based on comparisons to an appropriate standard,overall value of the advanced breeding lines, and number of successfulcultivars produced per unit of input (e.g., per year, per dollarexpended, etc.).

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars. Those still deficient in a few traits maybe used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to twelve years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and/or to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of garden bean plant breeding is to develop new, unique andsuperior garden bean cultivars. The breeder initially selects andcrosses two or more parental lines, followed by repeated selfing andselection, producing many new genetic combinations. Another method usedto develop new and unique bean cultivar occurs when the bean breederselects and crosses parental varieties followed by haploid induction andchromosome doubling that result in the development of dihaploidcultivars. The breeder can theoretically generate billions of differentgenetic combinations via crossing, selfing and mutations and the same istrue for the utilization of the dihaploid breeding method.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under unique and differentgeographical, climatic and soil conditions and further selections arethen made during and at the end of the growing season. The cultivarsthat are developed are unpredictable. This unpredictability is becausethe breeder's selection occurs in unique environments with no control atthe DNA level (using conventional breeding procedures or dihaploidbreeding procedures), and with millions of different possible geneticcombinations being generated. A breeder of ordinary skill in the artcannot predict the final resulting lines he develops, except possibly ina very gross and general fashion. This unpredictability results in theexpenditure of large amounts of research monies to develop superior newgarden bean cultivars.

The development of new garden bean cultivars requires the developmentand selection of garden bean varieties, the crossing of these varietiesand the evaluation of the crosses.

Pedigree breeding and recurrent selection breeding methods are used todevelop cultivars from breeding populations. Breeding programs combinedesirable traits from two or more cultivars or various broad-basedsources into breeding pools from which cultivars of desired phenotypesare developed by selfing and selection or through the dihaploid breedingmethod.

Pedigree breeding is used commonly for the improvement ofself-pollinating crops or inbred lines of cross-pollinating crops. Twoparents that possess favorable, complementary traits are crossed toproduce an F₁. An F₂ population is produced by selfing one or severalF₁s or by intercrossing two F₁s (sib mating). The dihaploid breedingmethod could also be used. Selection of the best individuals may beginin the F₂ population; then, beginning in the F₃, the best individuals inthe best families are selected. Replicated testing of families, orhybrid combinations involving individuals of these families, oftenfollows in the F₄ generation to improve the effectiveness of selectionfor traits with low heritability. At an advanced stage of inbreeding(i.e., F₆ and F₇), the best lines or mixtures of phenotypically similarlines are tested for potential release as new cultivars.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified, or created,by intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. The resulting plant isexpected to have the attributes of the recurrent parent (e.g., cultivar)and the desirable trait transferred from the donor parent. After theinitial cross, individuals possessing the phenotype of the donor parentare selected and repeatedly crossed (backcrossed) to the recurrentparent. The resulting plant is expected to have the attributes of therecurrent parent (e.g., cultivar) and the desirable trait transferredfrom the donor parent.

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂ individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

In a multiple-seed procedure, garden bean breeders commonly harvest oneor more pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster to thresh pods with a machine than to remove oneseed from each by hand for the single-seed procedure. The multiple-seedprocedure also makes it possible to plant the same number of seeds of apopulation each generation of inbreeding. Enough seeds are harvested tomake up for those plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., R. W. Allard, 1960, Principles of Plant Breeding, JohnWiley and Son, pp. 115-161; N. W. Simmonds, 1979, Principles of CropImprovement, Longman Group Limited; W. R. Fehr, 1987; Principles of CropDevelopment, Macmillan Publishing Co.; N. F. Jensen, 1988, PlantBreeding Methodology, John Wiley & Sons).

Proper testing should detect any major faults and establish the level ofsuperiority or improvement over current cultivars. In addition toshowing superior performance, there must be a demand for a new cultivarthat is compatible with industry standards or which creates a newmarket. The introduction of a new cultivar will incur additional coststo the seed producer, the grower, processor and consumer for specialadvertising and marketing, altered seed and commercial productionpractices, and new product utilization. The testing preceding release ofa new cultivar should take into consideration research and developmentcosts as well as technical superiority of the final cultivar. Forseed-propagated cultivars, it must be feasible to produce seed easilyand economically.

Garden bean, Phaseolus vulgaris L., is an important and valuablevegetable crop. Thus, a continuing goal of garden bean plant breeders isto develop stable, high yielding garden bean cultivars that areagronomically sound. The reasons for this goal are obviously to maximizethe amount of yield produced on the land. To accomplish this goal, thegarden bean breeder must select and develop garden bean plants that havetraits that result in superior cultivars.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the related art will become apparent to those of skill inthe art upon a reading of the specification.

When using a transgene, the trait is generally not incorporated intoeach newly developed line/cultivar such as bean cultivars H33121, H33122and/or H33124 by direct transformation. Rather, the more typical methodused by breeders of ordinary skill in the art to incorporate thetransgene is to take a line already carrying the transgene and to usesuch line as a donor line to transfer the transgene into the newlydeveloped line. The same would apply for a naturally occurring trait orone arising from spontaneous or induced mutations. The backcrossbreeding process of H33121 comprises the following steps: (a) crossingbean cultivars H33121 plants with plants of another cultivar thatcomprise the desired trait(s); (b) selecting the F₁ progeny plants thathave the desired trait(s); (c) crossing the selected F₁ progeny plantswith bean cultivars H33121 plants to produce backcross progeny plants;(d) selecting for backcross progeny plants that have the desiredtrait(s) and physiological and morphological characteristics of beancultivars H33121 to produce selected backcross progeny plants; and (e)repeating steps (c) and (d) one, two, three, four, five six, seven,eight, nine, or more times in succession to produce selected, second,third, fourth, fifth, sixth, seventh, eighth, ninth, or higher backcrossprogeny plants that consist essentially of the phenotypic andmorphological characteristics of bean cultivars H33121 and/or have allthe phenotypic and morphological characteristics of bean cultivarsH33121 and/or have the desired trait(s) and the physiological andmorphological characteristics of bean cultivars H33121 as determined inTable 1, including but not limited to at a 5% significance level whengrown in the same environmental conditions.

The bean plants produced by themethods are also part of the invention. Backcrossing breeding methods,well-known for one skilled in the art of plant breeding, will be furtherdeveloped in subsequent parts of the specification.

In a preferred embodiment, the present invention provides methods forincreasing and producing bean cultivars H33121, H33122 and/or H33124seed, whether by crossing a first parent bean cultivar plant with asecond parent bean cultivar plant and harvesting the resultant beanseed, wherein both said first and second parent bean cultivar plant arethe bean cultivars H33121, H33122 and/or H33124, respectively, or byplanting a bean seed of the bean cultivars H33121, H33122 and/or H33124,growing a bean cultivars H33121, H33122 and/or H33124 plant from saidseed, respectively, controlling a self pollination of the plant wherethe pollen produced by a grown bean cultivars H33121 plant pollinatesthe ovules produced by the very same bean cultivars H33121 grown plant,where the pollen produced by a grown bean cultivars H33122 plantpollinates the ovules produced by the very same bean cultivars H33122grown plant, where the pollen produced by a grown bean cultivars H33124plant pollinates the ovules produced by the very same bean cultivarsH33124 grown plant and harvesting the resultant seed.

Some of the selection criteria used for various generations include: podappearance and length, bean yield, pod set height, emergence, maturity,plant architecture, habit and height, seed yield, and quality anddisease resistance.

Bean Common Mosaic Virus resistance is a desired trait for a beanvariety. The disease occurs worldwide causing low quality of the harvestproduct and losses from 80% to 100% by reduction of yield. It is mostlytransmitted by aphids during the growing season, but can also be spreadby pollen or mechanically. The leaves develop mosaic patterns in whichirregular light and dark green patches are intermixed. Malformation andyellow dots may also be produced, often causing growth reduction. Theplant may be dwarfed and pod and seed yield reduced. Severe necrosis mayoccur and the plant may die if infected while young. Systemic necrosis,in which the roots and shoots become blackened, appears in cultivarshaving a dominant resistance gene (hypersensitive resistance mechanism).The systemic necrosis may spread to higher leaves without killing themor may be concentrated in the vascular parts of the stem, eventuallyleading to the death of all or part of the plant. When infection occurslate in plant development, parts of the plant may die and many pods mayshow brown discoloration in the pod wall and pod suture as a result ofvascular necrosis.

As used herein, the term “tissue culture” indicates a compositioncomprising isolated cells of the same or a different type or acollection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures are protoplasts, calli, plant clumps, and plantcells that can generate tissue culture that are intact in plants orparts of plants, such as embryos, pollen, flowers, seeds, pods, leaves,stems, roots, root tips, anthers, pistils and the like. Means forpreparing and maintaining plant tissue culture are well known in theart. By way of example, a tissue culture comprising organs has been usedto produce regenerated plants. U.S. Pat. Nos. 5,959,185, 5,973,234, and5,977,445 describe certain techniques, the disclosures of which areincorporated herein by reference.

With the advent of molecular biological techniques that have allowed theisolation and characterization of genes that encode specific proteinproducts, scientists in the field of plant biology developed a stronginterest in engineering the genome of plants to contain and expressforeign genes, or additional, or modified versions of native, orendogenous, genes (perhaps driven by different promoters) in order toalter the traits of a plant in a specific manner. Such foreignadditional and/or modified genes are referred to herein collectively as“transgenes.” Over the last fifteen to twenty years several methods forproducing transgenic plants have been developed and the presentinvention, in particular embodiments, also relates to transformedversions of the claimed variety or line.

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of, or operatively linked to, aregulatory element (for example, a promoter). The expression vector maycontain one or more such operably linked gene/regulatory elementcombinations. The vector(s) may be in the form of a plasmid and can beused alone or in combination with other plasmids to provide transformedgarden bean plants using transformation methods as described below toincorporate transgenes into the genetic material of the garden beanplant(s).

Expression Vectors for Garden Bean Transformation: Marker Genes

Expression vectors include at least one genetic marker operably linkedto a regulatory element (a promoter, for example) that allowstransformed cells containing the marker to be either recovered bynegative selection, i.e., inhibiting growth of cells that do not containthe selectable marker gene, or by positive selection, i.e., screeningfor the product encoded by the genetic marker. Many commonly usedselectable marker genes for plant transformation are well known in thetransformation arts, and include, for example, genes that code forenzymes that metabolically detoxify a selective chemical agent which maybe an antibiotic or an herbicide, or genes that encode an altered targetwhich is insensitive to the inhibitor. A few positive selection methodsare also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley, et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983). Anothercommonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen, et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase and aminoglycoside-3′-adenyltransferase, the bleomycin resistance determinant (Hayford, et al.,Plant Physiol., 86:1216 (1988); Jones, et al., Mol. Gen. Genet., 210:86(1987); Svab, et al., Plant Mol. Biol., 14:197 (1990); Hille, et al.,Plant Mol. Biol., 7:171 (1986)). Other selectable marker genes conferresistance to herbicides such as glyphosate, glufosinate or bromoxynil(Comai, et al., Nature, 317:741-744 (1985); Gordon-Kamm, et al., PlantCell, 2:603-618 (1990); and Stalker, et al., Science, 242:419-423(1988)).

Other selectable marker genes for plant transformation are not ofbacterial origin. These genes include, for example, mouse dihydrofolatereductase, plant 5-enolpyruvylshikimate-3-phosphate synthase and plantacetolactate synthase. Eichholtz, et al., Somatic Cell Mol. Genet.,13:67 (1987); Shah, et al., Science, 233:478 (1986); and Charest, etal., Plant Cell Rep., 8:643 (1990).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells rather than directgenetic selection of transformed cells for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include β-glucuronidase (GUS),β-galactosidase, luciferase, and chloramphenicol acetyltransferase(Jefferson, R. A., Plant Mol. Biol. Rep., 5:387 (1987); Teeri, et al.,EMBO J., 8:343 (1989); Koncz, et al., Proc. Natl. Acad. Sci. USA, 84:131(1987); DeBlock, et al., EMBO J., 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available. However, these in vivomethods for visualizing GUS activity have not proven useful for recoveryof transformed cells because of low sensitivity, high fluorescentbackgrounds and limitations associated with the use of luciferase genesas selectable markers.

A gene encoding Green Fluorescent Protein (GFP) has been utilized as amarker for gene expression in prokaryotic and eukaryotic cells (Chalfie,et al., Science, 263:802 (1994)). GFP and mutants of GFP may be used asscreenable markers.

Expression Vectors for Garden Bean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element, for example, a promoter.Several types of promoters are well known in the transformation arts asare other regulatory elements that can be used alone or in combinationwith promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred.”Promoters that initiate transcription only in a certain tissue arereferred to as “tissue-specific.” A “cell-type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may effect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell-type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter that is active under mostenvironmental conditions.

A. Inducible Promoters—An inducible promoter is operably linked to agene for expression in garden bean. Optionally, the inducible promoteris operably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in garden bean. Withan inducible promoter the rate of transcription increases in response toan inducing agent.

Any inducible promoter can be used in the instant invention. See, Ward,et al., Plant Mol. Biol., 22:361-366 (1993). Exemplary induciblepromoters include, but are not limited to, that from the ACEI systemwhich responds to copper (Mett, et al., Proc. Natl. Acad. Sci. USA,90:4567-4571 (1993)); In2 gene from maize which responds tobenzenesulfonamide herbicide safeners (Gatz, et al., Mol. Gen. Genetics,243:32-38 (1994)), or Tet repressor from Tn10 (Gatz, et al., Mol. Gen.Genetics, 227:229-237 (1991)). A particularly preferred induciblepromoter is a promoter that responds to an inducing agent to whichplants do not normally respond. An exemplary inducible promoter is theinducible promoter from a steroid hormone gene, the transcriptionalactivity of which is induced by a glucocorticosteroid hormone (Schena,et al., Proc. Natl. Acad. Sci. USA, 88:0421 (1991)).

B. Constitutive Promoters—A constitutive promoter is operably linked toa gene for expression in garden bean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in garden bean.

Many different constitutive promoters can be utilized in the instantinvention. Exemplary constitutive promoters include, but are not limitedto, the promoters from plant viruses such as the 35S promoter from CaMV(Odell, et al., Nature, 313:810-812 (1985)) and the promoters from suchgenes as rice actin (McElroy, et al., Plant Cell 2, 163-171 (1990));ubiquitin (Christensen, et al., Plant Mol. Biol., 12:619-632 (1989) andChristensen, et al., Plant Mol. Biol., 18:675-689 (1992)); pEMU (Last,et al., Theor. Appl. Genet., 81:581-588 (1991)); MAS (Velten, et al.,EMBO J., 3:2723-2730 (1984)) and maize H3 histone (Lepetit, et al., Mol.Gen. Genetics, 231:276-285 (1992) and Atanassova, et al., Plant Journal,2 (3):291-300 (1992)). The ALS promoter, Xba1/Ncol fragment 5′ to theBrassica napus ALS3 structural gene (or a nucleotide sequence similarityto said Xba1/Ncol fragment), represents a particularly usefulconstitutive promoter. See, PCT Application WO 96/30530.

C. Tissue-specific or Tissue-preferred Promoters—A tissue-specificpromoter is operably linked to a gene for expression in garden bean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in garden bean. Plants transformed with a geneof interest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in theinstant invention. Exemplary tissue-specific or tissue-preferredpromoters include, but are not limited to, a root-preferred promotersuch as that from the phaseolin gene (Murai, et al., Science, 23:476-482(1983) and Sengupta-Gopalan, et al., Proc. Natl. Acad. Sci. USA82:3320-3324 (1985)); a leaf-specific and light-induced promoter such asthat from cab or rubisco (Simpson, et al., EMBO J., 4(11):2723-2729(1985) and Timko, et al., Nature, 318:579-582 (1985)); ananther-specific promoter such as that from LAT52 (Twell, et al., Mol.Gen. Genetics, 217:240-245 (1989)); a pollen-specific promoter such asthat from Zm13 or a microspore-preferred promoter such as that from apg(Twell, et al., Sex. Plant Reprod., 6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of protein produced by transgenes to a subcellular compartmentsuch as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall, ormitochondrion or for secretion into the apoplast, is accomplished bymeans of operably linking the nucleotide sequence encoding a signalsequence to the 5′ and/or 3′ region of a gene encoding the protein ofinterest. Targeting sequences at the 5′ and/or 3′ end of the structuralgene may determine during protein synthesis and processing where theencoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See, forexample, Becker, et al., Plant Mol. Biol., 20:49 (1992); Knox, C., etal., “Structure and Organization of Two Divergent Alpha-Amylase Genesfrom Barley,” Plant Mol. Biol., 9:3-17 (1987); Lerner, et al., PlantPhysiol., 91:124-129 (1989); Fontes, et al., Plant Cell, 3:483-496(1991); Matsuoka, et al., Proc. Natl. Acad. Sci., 88:834 (1991); Gould,et al., J. Cell. Biol., 108:1657 (1989); Creissen, et al., Plant J.,2:129 (1991); Kalderon, et al., Cell, 39:499-509 (1984); Steifel, etal., “Expression of a maize cell wall hydroxyproline-rich glycoproteingene in early leaf and root vascular differentiation,” Plant Cell,2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem., 114:92-6(1981).

According to a preferred embodiment, the transgenic plant provided forcommercial production of foreign protein is a garden bean plant. Inanother preferred embodiment, the biomass of interest is seed. For therelatively small number of transgenic plants that show higher levels ofexpression, a genetic map can be generated, primarily via conventionalRFLP, PCR and SSR analysis, which identifies the approximate chromosomallocation of the integrated DNA molecule. For exemplary methodologies inthis regard, see Methods in Plant Molecular Biology and Biotechnology,Glick and Thompson Eds., CRC Press, Inc., Boca Raton, 269:284 (1993).Map information concerning chromosomal location is useful forproprietary protection of a subject transgenic plant. If unauthorizedpropagation is undertaken and crosses made with other germplasm, the mapof the integration region can be compared to similar maps for suspectplants, to determine if the latter have a common parentage with thesubject plant. Map comparisons would involve hybridizations, RFLP, PCR,SSR, and sequencing, all of which are conventional techniques.

Likewise, by means of the present invention, agronomic genes can beexpressed in transformed plants. More particularly, plants can begenetically engineered to express various phenotypes of agronomicinterest. Exemplary genes implicated in this regard include, but are notlimited to, those categorized below:

1. Genes that Confer Resistance to Pests or Disease and that Encode:

A. Plant disease resistance genes. Plant defences are often activated byspecific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with one ormore cloned resistance genes to engineer plants that are resistant tospecific pathogen strains. See, for example, Jones, et al., Science,266:789 (1994) (cloning of the tomato Cf-9 gene for resistance toCladosporium fulvum); Martin, et al., Science, 262:1432 (1993) (tomatoPto gene for resistance to Pseudomonas syringae pv. tomato encodes aprotein kinase); Mindrinos, et al., Cell, 78:1089 (1994) (ArabidopsisRSP2 gene for resistance to Pseudomonas syringae).

N. A viral-invasive protein or a complex toxin derived therefrom. Forexample, the accumulation of viral coat proteins in transformed plantcells imparts resistance to viral infection and/or disease developmenteffected by the virus from which the coat protein gene is derived, aswell as by related viruses. See, Beachy, et al., Ann. Rev. Phytopathol.,28:451 (1990). Coat protein-mediated resistance has been conferred upontransformed plants against alfalfa mosaic virus, cucumber mosaic virusand tobacco streak virus, potato virus X, potato virus Y, tobacco etchvirus, tobacco rattle virus, and tobacco mosaic virus. Id.

O. An insect-specific antibody or an immunotoxin derived therefrom.Thus, an antibody targeted to a critical metabolic function in theinsect gut would inactivate an affected enzyme, killing the insect.

Exemplary genes in this category codefor mutant ALS and AHAS enzyme as described, for example, by Lee, etal., EMBO J., 7:1241 (1988), and Miki, et al., Theor. Appl. Genet.,80:449 (1990), respectively.

Methods for Garden Bean Transformation

Numerous methods for plant transformation have been developed includingbiological and physical plant transformation protocols. See, forexample, Miki, et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). Inaddition, expression vectors and in-vitro culture methods for plant cellor tissue transformation and regeneration of plants are available. See,for example, Gruber, et al., “Vectors for Plant Transformation” inMethods in Plant Molecular Biology and Biotechnology, Glick and ThompsonEds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A. Agrobacterium-mediated Transformation—One method for introducing anexpression vector into plants is based on the natural transformationsystem of Agrobacterium. See, for example, Horsch, et al., Science,227:1229 (1985); Diant, et al., Molecular Breeding, 3:1, 75-86 (1997).A. tumefaciens and A. rhizogenes are plant pathogenic soil bacteriawhich genetically transform plant cells. The Ti and Ri plasmids of A.tumefaciens and A. rhizogenes, respectively, carry genes responsible forgenetic transformation of the plant. See, for example, Kado, C.I., Crit.Rev. Plant Sci., 10:1 (1991). Descriptions of Agrobacterium vectorsystems and methods for Agrobacterium-mediated gene transfer areprovided by Gruber, et al., supra, Miki, et al., supra, and Moloney, etal., Plant Cell Reports, 8:238 (1989). See also, U.S. Pat. No. 5,591,616issued Jan. 7, 1997.

B. Direct Gene Transfer—Despite the fact the host range forAgrobacterium-mediated transformation is broad, some cereal or vegetablecrop species and gymnosperms have generally been recalcitrant to thismode of gene transfer, even though some success has been achieved inrice and corn. Hiei, et al., The Plant Journal, 6:271-282 (1994) andU.S. Pat. No. 5,591,616 issued Jan. 7, 1997. Several methods of planttransformation, collectively referred to as direct gene transfer, havebeen developed as an alternative to Agrobacterium-mediatedtransformation. A generally applicable method of plant transformation ismicroprojectile-mediated transformation where DNA is carried on thesurface of microprojectiles measuring 1 to 4 microns. The expressionvector is introduced into plant tissues with a biolistic device thataccelerates the microprojectiles to speeds of 300 to 600 m/s which issufficient to penetrate plant cell walls and membranes. Russell, D. R.,et al., Pl. Cell. Rep., 12, 165-169 (3 Jan. 1993); Aragao, F. J. L., etal., Plant Mol. Biol., 20, 357-359 (2 Oct. 1992); Aragao, Theor. Appl.Genet., 93:142-150 (1996); Kim, J.; Minamikawa, T., Plant Science,117:131-138 (1996); Sanford, et al., Part. Sci. Technol., 5:27 (1987);Sanford, J. C., Trends Biotech., 6:299 (1988); Klein, et al., Bio/Tech.,6:559-563 (1988); Sanford, J. C., Physiol Plant, 7:206 (1990); Klein, etal., Biotechnology, 10:268 (1992).

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang, et al., Bio/Technology, 9:996 (1991).Alternatively, liposome and spheroplast fusion have been used tointroduce expression vectors into plants. Deshayes, et al., EMBO J.,4:2731 (1985); Christou, et al., Proc Natl. Acad. Sci. USA, 84:3962(1987). Direct uptake of DNA into protoplasts using CaCl₂ precipitation,polyvinyl alcohol or poly-L-ornithine have also been reported. Hain, etal., Mol. Gen. Genet., 199:161 (1985) and Draper, et al., Plant CellPhysiol., 23:451 (1982). Electroporation of protoplasts and whole cellsand tissues have also been described Saker, M. and Kuhne, T., BiologiaPlantarum, 40(4):507-514 (1997/98); D'Halluin, et al., Plant Cell,4:1495-1505 (1992); and Spencer, et al., Plant Mol. Biol., 24:51-61(1994)).

Following transformation of garden bean target tissues, expression ofthe above-described selectable marker genes allows for preferentialselection of transformed cells, tissues and/or plants, usingregeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed with another (non-transformed or transformed) variety in orderto produce a new transgenic variety. Alternatively, a genetic trait thathas been engineered into a particular garden bean line using theforegoing transformation techniques could be moved into another lineusing traditional backcrossing techniques that are well known in theplant breeding arts. For example, a backcrossing approach could be usedto move an engineered trait from a public, non-elite variety into anelite variety, or from a variety containing a foreign gene in its genomeinto a variety or varieties that do not contain that gene. As usedherein, “crossing” can refer to a simple X by Y cross or the process ofbackcrossing depending on the context.

Backcrossing

When the term garden bean plant, cultivar or bean line are used in thecontext of the present invention, this also includes cultivars where oneor more desired traits has been introduced through backcrossing methods,whether such trait is a naturally occurring one or a transgenic one.Backcrossing methods can be used with the present invention to improveor introduce a characteristic into the line. The term “backcrossing” asused herein refers to the repeated crossing of a hybrid progeny back tothe recurrent parent, i.e., backcrossing one, two, three, four, five,six, seven, eight, nine, or more times to the recurrent parent. Theparental bean plant which contributes the gene for the desiredcharacteristic is termed the nonrecurrent or donor parent. Thisterminology refers to the fact that the nonrecurrent parent is used onetime in the backcross protocol and therefore does not recur. Theparental bean plant to which the gene or genes from the nonrecurrentparent are transferred is known as the recurrent parent as it is usedfor several rounds in the backcrossing protocol.

In a typical backcross protocol, the original cultivar of interest(recurrent parent) is crossed to a second line (nonrecurrent parent)that carries the gene or genes of interest to be transferred. Theresulting progeny from this cross are then crossed again to therecurrent parent and the process is repeated until a garden bean plantis obtained wherein essentially all of the desired morphological andphysiological characteristics of the recurrent parent are recovered inthe converted plant, generally determined at a 5% significance levelwhen grown in the same environmental condition, in addition to the geneor genes transferred from the nonrecurrent parent. It has to be notedthat some, one, two, three, or more, self-pollination and growing ofpopulation might be included between two successive backcrosses. Indeed,an appropriate selection in the population produced by theself-pollination, i.e., selection for the desired trait andphysiological and morphological characteristics of the recurrent parentmight be equivalent to one, two or even three, additional backcrosses ina continuous series without rigorous selection, saving time, money andeffort to the breeder. A non limiting example of such a protocol wouldbe the following: (a) the first generation F₁ produced by the cross ofthe recurrent parent A by the donor parent B is backcrossed to parent A;(b) selection is practiced for the plants having the desired trait ofparent B; (c) selected plants are self-pollinated to produce apopulation of plants where selection is practiced for the plants havingthe desired trait of parent B and the physiological and morphologicalcharacteristics of parent A; (d) the selected plants are backcrossedone, two, three, four, five, six, seven, eight, nine, or more times toparent A to produce selected backcross progeny plants comprising thedesired trait of parent B and the physiological and morphologicalcharacteristics of parent A. Step (c) may or may not be repeated andincluded between the backcrosses of step (d).

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalline. To accomplish this, a gene or genes of the recurrent cultivar ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphological,constitution of the original line. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross, one ofthe major purposes is to add some commercially desirable, agronomicalimportant trait to the plant. The exact backcrossing protocol willdepend on the characteristic or trait being altered to determine anappropriate testing protocol. Although backcrossing methods aresimplified when the characteristic being transferred is a single geneand dominant allele, multiple genes and recessive allele(s) may also betransferred and therefore, backcross breeding is by no means restrictedto character(s) governed by one or a few genes. In fact the number ofgenes might be less important than the identification of thecharacter(s) in the segregating population. In this instance it may thenbe necessary to introduce a test of the progeny to determine if thedesired characteristic(s) has been successfully transferred. Such testsencompass visual inspection, simple crossing but also follow up of thecharacteristic(s) through genetically associated markers and molecularassisted breeding tools. For example, selection of progeny containingthe transferred trait is done by direct selection, visual inspection fora trait associated with a dominant allele, while the selection ofprogeny for a trait that is transferred via a recessive allele requiresselfing the progeny to determine which plant carries the recessiveallele(s).

Many single gene traits have been identified that are not regularlyselected for in the development of a new line but that can be improvedby backcrossing techniques. Single gene traits may or may not betransgenic. Examples of these traits include, but are not limited to,herbicide resistance (such as bar or pat genes), resistance forbacterial, fungal, or viral disease (such as gene I used for BCMVresistance), insect resistance, enhanced nutritional quality (such as 2salbumine gene), industrial usage, agronomic qualities (such as the“persistent green gene”), yield stability, and yield enhancement. Thesegenes are generally inherited through the nucleus. Some other singlegene traits are described in U.S. Pat. Nos. 5,777,196, 5,948,957, and5,969,212, the disclosures of which are specifically hereby incorporatedby reference.

In 1981 the backcross method of breeding accounted for 17% of the totalbreeding effort for inbred corn line development in the United States,according to, Hallauer, A. R., et al., “Corn Breeding,” Corn and CornImprovement, No. 18, pp. 463-481 (1988).

The backcross breeding method provides a precise way of improvingvarieties that excel in a large number of attributes but are deficientin a few characteristics. (Page 150 of the Pr. R. W. Allard's 1960 book,Principles of Plant Breeding, published by John Wiley & Sons, Inc.) Themethod makes use of a series of backcrosses to the variety to beimproved during which the character or the characters in whichimprovement is sought is maintained by selection. At the end of thebackcrossing the gene or genes being transferred unlike all other genes,will be heterozygous. Selfing after the last backcross produceshomozygosity for this gene pair(s) and, coupled with selection, willresult in a variety with exactly the adaptation, yielding ability, andquality characteristics of the recurrent parent but superior to thatparent in the particular characteristic(s) for which the improvementprogram was undertaken. Therefore, this method provides the plantbreeder with a high degree of genetic control of his work.

The backcross method is scientifically exact because the morphologicaland agricultural features of the improved variety could be described inadvance and because the same variety could, if it were desired, be breda second time by retracing the same steps (Briggs, “Breeding wheatsresistant to bunt by the backcross method,” Jour. Amer. Soc. Agron.,22:289-244 (1930)).

Backcrossing is a powerful mechanism for achieving homozygosity and anypopulation obtained by backcrossing must rapidly converge on thegenotype of the recurrent parent. When backcrossing is made the basis ofa plant breeding program, the genotype of the recurrent parent will bemodified only with regards to genes being transferred, which aremaintained in the population by selection.

Successful backcrosses are, for example, the transfer of stem rustresistance from ‘Hope’ wheat to ‘Bart’ wheat and even pursuing thebackcrosses with the transfer of bunt resistance to create ‘Bart 38’,having both resistances. Also highlighted by Allard is the successfultransfer of mildew, leaf spot and wilt resistances in ‘CaliforniaCommon’ alfalfa to create ‘Caliverde’. This new ‘Caliverde’ varietyproduced through the backcross process is indistinguishable from‘California Common’ except for its resistance to the three nameddiseases.

One of the advantages of the backcross method is that the breedingprogram can be carried out in almost every environment that will allowthe development of the character being transferred.

The backcross technique is not only desirable when breeding for diseaseresistance but also for the adjustment of morphological characters,color characteristics, and simply inherited quantitative characters,such as earliness, plant height, and seed size and shape. In thisregard, a medium grain type variety, ‘Calady’, has been produced byJones and Davis. As dealing with quantitative characteristics, theyselected the donor parent with the view of sacrificing some of theintensity of the character for which it was chosen, i.e., grain size.‘Lady Wright’, a long grain variety was used as the donor parent and‘Coloro’, a short grain variety as the recurrent parent. After fourbackcrosses, the medium grain type variety ‘Calady’ was produced.
